pyenv slides from PyOhio

I gave a lightning talk last night here at PyOhio
introducing pyenv and a brief
overview of the unique kinds of problems that my old standard of
project isolation—a Homebrewed Python and
virtualenv—yielded.

About 16 hours later, I've actually got around to unstuffing my
liquidluck virtualenv
by converting it to pyenv. As a result, I can now share the slides
with you!
